To all whom it may concern:

Be it known that I, WOLFGANG Biisnnnn, citizen of Germany. residing'at Lichten-- chain (Schwarzburg-Rudolstadt) Germany,

have invented certain new and useful 1m: proyements in Double Compounds ot Rail way Lines (for which 1 have filed application in Germany, Jan. 1, 1918; Austrla, Dec.

23, 1918; Switzerland, Dec. 7 27, 1918; 10 Sweden, Dec. 28, 1918; Hungary, Jan. 2, 1919; Denmark, Jan. 2, '1919;I-1olland, Jan. 1, 1919; Finland, Jan. 13, 1919; Norway, Jan. 21, 1919; Italy, Feb. 6, 1919; France, Feb. 21, 1919'; Luxemburg, Feb. 26, 1919; Belgium, Apr. 30, 1920 Great Britain, May 29, 1920; Czechoslovakia, July 7, 1920; F0- land, July 8. 1920), of which the following is a specification.

\This invention relates to double-slip switches commonly used at railroad cross in large railroad terminals having many tracks it is frequently desirable to provide switching facilities between tracks remote from each other and even between the tracks at opposite sides, but a continuous switch track interconnecting all tracks is out of the question with switches usually employed, having a switch angle of approximately 12 9 because the length of sucha switch track would be prohibitive in many cases.

Assuming for instance that it is desired at a terminal station to connect twenty tracks, spaced about 15 feet apart from center to center, by means of a switching track, this would require a length of 98 1 feet in the case of a switch angle 1:9, which length is ordinarily not available. A system, moreover, of the type referred to would be too complex to be controlled by one shifting gangforeman only and would introduce difficulties of operation, delays and danger.

Itis the object of this invention to provide aswitch system including a single switching track between remote tracks of an extended track system which is relatively short and simple in construction and operation. 7

F or a full understanding of the invention reference is had to the accompanying drawings in which Fig. 1 is a plan view of a single track intersection; T

Fig. 2 is a section on a larger scale of a tongue forming an important detail of; the invention; and y l I F ig. 3 is a transverse'section on the. line Fig. 2. J

Fig. 1 indicates diagrammatically two parallel tracks and a switch track for interconnecting the' same. It is understood that the two parallel tracks are representative of any plurality of parallel tracks the relation between the switching track and each of the parallel tracks being identical.

In the'drawin s ab 0 cl designate the so called crossing square by which is meant the quadrangle or diamond defin'edby the intersections of the rails of two tracks.

While in ordinary constructions of this type the switch curves or slips lie entirely within the crossing square, it is a characteristic feature of this invention that parts of he switching curves extend beyond and lie outside the crossing square.

Another characteristic feature is a single double-tread rail 6 extending diagonally across the crossing square.

In the arrangement illustrated the ends 7" of the slip rails extend materially beyond the points a and c of the crossing quadrangle. The curved stock rail portions Z and 70, as can be readily seen, curve away from the straight line of the respective tracks a substantial distance outwardly from the line which passes through the points a and 0 respectively parallel to the ties. The curved portions Z and 7c are thus moved away from the intersection points (Z and b respectively as compared with the practice according to the prior art, and the parts of the portions Z and Z3 which are co-extensive with the length of the. crossing quadrangle a b 0 (Z have such a large radius of vcurvature that they approach straight lines. This dis position of the curved portions Z and Z; leads to the use of a single rail a forming the diagonal of the crossing quadrangle. The rail 6 is in fact a combination, of two rails forming the mates of the curved portions Z 5 and 70 respectively. The tread portion of the rail 6 facing the portion Z is parallel the tread portion facing the Jarallel to the latter. The ends orm continuations of the rail 6 and exto the points at which the portions away from straight lines serve purpose of cont oiling the direc- 'l e and actions 7 are so large'terminal station are obvious.

In the foregoing the invention has been described merely by way oi 'ipisnd it is understood that the arrangement terming the invention is susceptible of various changes and modifications in accordance with varying conditions to. he met.

I claim: 7 i

1. In a railroad crossing switch the combination with two tracks crossing each other (that the two tracks, of a common center rail cooperating with both curved rails to define switching tracks and movable switch sections extending from each end or" the common rail and forming continuations thereof.

2. In a railroad crossing switch, the comhination with two tracks crossing each other defining thereby a crossing quadrangle, and

and outer curved rails, each forming part ot' outer curved rails, each forming part of the two tracks, of a common center rail ands thereof, co-operating with the other curved rail. I

3. In a railroad crossing switch, thecombin tion with two tracks crossing each other deli ing thereby a crossing quadrangle, and outer curved rails forming part oi the two tracl is, of means co-operating with the said curved rails for providing switching tracks, said means includin movable switch sections extending outwardly from each of opposite corners or the quadrangle and a com mon rail having a tread portion on each side one tread in conjunction with one of 'fl switch sections at each end co-operating with one of said curved rails and the other tread in conjunction with the other switch section at each end co-operating with the othecurved rail.

In a railroad crossing switch, thecoznbination with two tracks crossing each other defining thereby a crossing quadrangle and outer curved rails'forrning a part or each track, of means co-operating with the saie curved rails for providing switching tracks, said means includingimovable switch sections extendingoutwardly from opposite 5. In a railroad crossing switch, thecozrbnation with two tracks crossing each other L, and thereby defining a-crossing quadrangle and outer curved rails forming a part of each track, or solid blocks in the acute angled corners of the quadrangle embodying each three tongue tips, and movahle'switch sections extending outwardly from each block for co-operation with the two tracks respectively.
